Why can't the kernel do that too? The only reason I didn't move that into the kernel in the MGA driver is that it would have required too much *more* code surgery in the DDX. I very strongly believe that the right model moving forward is for user-mode to say to the kernel, "I beg of thee. Initialize thyne self." Over the years we've had serveral cases where the user / kernel initialization dance has needed to change, and this has resulted in numerous backwards-compatability nightmares. Moving the whole dance into the kernel won't eliminate all of them, but it will certainly reduce them (IMO). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCtvO3X1gOwKyEAw8RAiMoAJ9/FatEuR3ObELyHgS6JsYDeBvVywCdHKTK gxhCmJLPX9eI9VOCN4jIhEs= =g0NF -----END PGP SIGNATURE----- ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
